4 Claims.

This invention relates to a valve manifold which consists of anintegrally cast body, suitably cored to provide a plurality of passageseach having a valve for controlling the flow of fluid therethrough. Theinvention is shown as applied to the fuel distributing jet of a stoker,although its use is not restricted to any particular installation.

It is an object of my invention to provide a simple and compact manifoldthat can be cast with a minimum of uneven shrinkage and that will notspring out of shape when the casting is cooled.

It is another object of the invention to provide a novel manifoldthatcombines compactness with a maximum of strength and rigidity andthat can be economically constructed.

Other objects and advantages of the invention will become apparent fromthe following description and theaccompanyingdrawings.

Referring to the drawings:

Fig. 1 is a fragmentary view in centralvertical section through a stokerembodying a pressure fluid distributing means, with certain portions ofthat Stoker in elevation, and in which construction, the novel manifoldis employed;

Fig. 2 is a sectional view on the line 2-2 of Fig. 1 with the'manifoldshown in elevation;

Fig. 3 is a sectional view of the manifold taken on the line 3-3 of Fig.2; I

Fig. 4 is a sectional view taken on the line 44 of Fig. 3;'

Fig. 5 is a sectional view taken on the irregular line 5-5 of Fig. 4;and

Fig. 6 is a sectional view taken on the line 66 of Fig. 4.

Referring particularly to Figs. 1 and 2 of the drawings, a stokerdischarge conduit is shown at I0, communicating with an opening II inthe wall I2 of a furnace I3, such as that of a locomotive boiler. Thedischarge conduit I0 delivers fuel onto a distributing plate I4 disposedin the opening I I' and from which plate the fuel is projected into thefurnace to the various parts of the firebed by blasts of fluid underpressure issuing from the pressure fluid jet member. I5.

The jet member I5 is provided with a plurality of separated chambers,such as I6, I'I, I8, I9 and 20, arranged to receive fluid under pressurefrom a suitable source ofsupply through the pipes IGa, IIa, I81, I91;and 20a, respectively. The blasts of .pressure fluid for projecting fuelfrom the plate I4 issue from the jet openings 2| of the jet mem-' berI5, a plurality of such jet openings, preferably, communicating witheach of the chamber I6, I'I, I8, I9 and 20.

The streams of pressure fluid issuing from the jet openings of theseveral chambers are directed toward predetermined areas of the firebed,and in 5 order to provide for adequate control of the intensity of theseblasts for effecting proper control of fuel distribution, delivery ofpressure fluidto the pipes I6a, Ila, I8a, I90. and 20a is controlled byvalves, designated respectively as IE1), I'Ib, I8b, 10 I91) and 20b,each of which is manually controlled and carried by the manifold M. Themanifold M receives pressure fluid from a suitable source of supply,such as the boiler of the locomotive, through the main lead 22. Withinthe body por- 15 tion 23 of the manifold'M, there is provided a chamber24 receiving pressure fluid from the main lead 22. The pressure fluidpasses from the chamber 24 into a cored triangular-shaped endlesspassage 25 formed in the manifold body 23 through an opening 26 whichisv manually controlled by the main valve 21 carried by the manifold.

The pipes IGa, IIa, I8a, I91; and 20a are screwed into the manifold Mand communicate with the 3 passage 25 through the respective secondarypassages I6c, IIc, I90, I and 200 therein. The passages I6c,iIJc, I 8c,I90 and 200 are separated from the main passage 25 by the partition I6d, IId, I 8d, I9d and 20d, respectively, and pressure fluid passes fromthe main passage 25 to the secondary passages through the openings IBe,I'Ie, I8e, I9e

and 29e, in the partitions IGd, I'Id, I8d, I9d and 2011, respectively,the size of the openings being manually controlled by the valves I 6b,I'Ib, I8b, I9b and 20b, respectively. The manifold M is secured to thelocomotive backhead I2 by suitable means, such as the threaded bolts 40passing through the web M and bosses 42 formed with the body portion 23of the manifold. 40

Each of the valves, including the main valve 21, comprises a stem 29threaded into a bonnet 29, the stem having a valve member 30 at itsinner end and the valve handle 3| at its outer end. A valve'seat 32 isthreaded into the body portion of the manifold between the passage 25and each of the passages I60, I10, I90, I90 and 200, and between thechamber 24 and passage 25. Thus, pressure fluid will pass into thepassage 25 and 50 the passages I60, I 'Ic, I 80, I 90 and 200 at variouspressures determined by the setting of the valves.

The manifold embodying an endless main passage 25 is extremely compactand can be secured or interference with other equipment. Theconstruction of the manifold insures against uneven shrinkage andundesired springing or warping out of shape when the manifold is castand cooled.'
